2.3 Sealing the Base

To prevent condensation and infestation in the controller cabinet the base MUST be sealed as soon
as possible after the controller has been installed. If any of the cables were replaced or moved during
the installation of the controller the kiln dried sand in-filling must be made good before the sealing
compound is introduced.
Siemens base seal kit part number 667/1/20214/000 OR GB7:4/MC3584 SEALANT ISP PC5882-BLACK
is recommended for sealing the base.
Guidance for In-Filling
The in-filling, kiln dried sand, must be brought to ground level or above and compacted. Make sure that the
kiln dried sand is level or slightly sloped down where it meets the cables so it will not prevent the sealant
meeting the cable.
The sealant should be poured all around the cables and to a height which, when the sealant is set,
gives a total covering not less than 6.5mm thick over the base of the controller cabinet base. Use
between 2.0 to 3.0 litres of approved epoxy resin for the large controller cabinet base and 2.0 Litres
for the small controller cabinet base this will give an adequate and even cover.
This will act as a preventative barrier against the ingress of moisture and animal/insect infestation.
A concrete fillet around the outside of the stool may be completed before or after the epoxy sealing
to suit site conditions.
Protection of Circuits
Should the controller cabinet base/stool NOT be in-filled with kiln dried sand and sealed with an approved
epoxy resin the controller electronics/electrical circuits may be damaged.
